摘要

Procedure for purifying aqueous solutions of precipitating metal ions, such as arsenides, antimonides, teluros, selenides and tin and mercury alloys, where arsenic, antimony, tellurium, selenium, tin, mercury and mercury are added to the aqueous solution as auxiliary agents. Or compounds thereof, after which the impurities are precipitated under reducing conditions with the help of the auxiliary agent, characterized in that the cementation is catalyzed by means of the cementation formed by the contact of the aqueous solution with the cemented one, the amount of which is substantially greater than the amount cemented first from the aqueous solution.
